1. Coyote: larger one is front track. Is this a left hind (I see a leading toe) and a right front? 2. Racoon (and a coyote going the opposite direction) 3. Left hind 4. Owl, but I don't know the difference between species yet. Barred? 5. Nutria 6. It's hard to make out here, but I think that one deep point is the middle toe of the hind foot, and the round, bulbous imprints are front feet. 7. Great Blue Heron? 8. Right foot 9. Eagle? Turkey vulture? 10. Right foot 11. Big game bird...? 12. Deer mouse 13. Bound 14. Really blown out... overall shape and size makes me think gray fox. The stride is short, 4", which is even a bit below the short end of Elbroch's range for a gray fox walk (6-10"), so that ruled out red fox and coyote. 15. Some kind of beetle that walked across the sand and then burrowed into it? 16. This looks like a porcupine drag that has wiped out any tracks that were left. I do see something that could be the pebbly pad of a porcupine a little bit off to the right from the main drag. 17. Don't know what kind of bird this is. Seems too big to be a crow... 18. ? Long drag makes it look like a walk. 19. Coyote. This track is more splayed than most coyote tracks I've seen, but given the substrate that makes sense. The nails seem to pointy to be domestic dog. 20. Front right. You can see the leading toe. I think it's a front foot because of the splay, and it looks a little on the big side to be a hind. 21. Ground squirrel 22. I don't know how you would tell the direction of travel here. Tips?
